Word Origin & History

cast c.1230, from O.N. kasta "to throw." The noun sense of "a throw" (c.1300) carried an idea of the form the thing takes after it has been thrown, which led to varied meanings, such as "group of actors in a play" (1631). OED finds 42 distinct noun meaning and 83 verbal ones, with many sub-definitions. A cast in the eye preserves the older sense of "warp, turn," in which it replaced O.E. weorpan (see warp), and is itself largely superseded now by throw. Still used of fishing line and glances.
